The complete timeline from the first idea to Batch #002.
The idea is born
Somewhere around kilometer five of a morning run, the idea clicked: what if we let an AI agent brew a beer? Not as a gimmick, but as a real proof of concept. Gerhard has the brewery, Frontira has the AI tooling, and OpenClaw can talk to hardware over BLE. By the end of the run the name was set. Lobster Lager. Hold my claw.
First BLE connection to Grainfather
Prototype day. Connected a MacBook to Gerhard's Grainfather G30 over Bluetooth Low Energy for the first time. Read live sensor data, toggled the pump, sent temperature commands. The bridge works. OpenClaw can see and control the hardware while Gerhard stays in charge of the physical process.
Recipe finalized with Gerhard
Sat down with Gerhard and dialed in the recipe using kleiner-brauhelfer. An Amber Lager built on Pilsner and Munich malts, with Caramel Amber and Melanoidin for depth. Mandarina Bavaria for a citrus edge, East Kent Goldings for earthy balance. 24.5 liters, 4.6% ABV, 20 IBU. Lobster Lager V0 is locked.
Website and newsletter live
lobsterlager.com is up. The full story, the recipe with grain bill and hop schedule, and the founders list. Sharing everything openly from day one. If you want to follow along or grab a spot at the tasting, this is where it starts.
Batch #001 founders release opens
The Founders 6-Pack and Tasting Ticket went live through Stripe Checkout. Both were part of Batch #001, which is now complete and sold out.
First test brew: mash running
Fired up the Grainfather for the first test run. OpenClaw managed the full mash schedule through the Brew Dashboard. Mash in, then malt rest at 63 °C, with every step automated. Pump on, heater on, temperature holding steady. The system works end to end.
Brew Dashboard goes live
The Brew Dashboard ran its first real session. Live temperature, step progress, timer countdown, pump and heater status. OpenClaw monitored everything in real time. Multiple recipes loaded and ready. The control layer is proven.
HAIL THE CRUSTACEAN 🦞 REVOLUTION
Presenting Lobster Lager at the first ever OpenClaw Conf Vienna, organized by Peter Steinberger, creator of OpenClaw. Twelve 5-minute talks on creative AI use cases. Ours: we brewed a beer with an AI agent. Tribüne / Prisma, 500 people, live on stage.
OpenClaw gets eyes
Gerhard mounted a camera next to the Grainfather. OpenClaw can now visually monitor the brew process, reading the display temperature and checking foam levels during the boil. BLE for control, vision for verification. The claw sees everything.
brewOS gets stats and vision
Major dashboard upgrade. The Brew Dashboard now shows live brew stats, step history, and integrated vision feedback. Clawdbot, the Telegram bot, walks the brewer through every action: start, acknowledge, skip, abort. OpenClaw doesn’t just control the hardware anymore. It explains what’s happening and why. The full brew operating system is taking shape.
36kr covers the conference
Chinese tech publication 36kr picked up the OpenClaw Conf Vienna story. Their coverage highlighted the beer brewing demo: an AI agent that can not only brew beer but run half a design company. From a 500-person venue in Vienna to Chinese tech media.

Final recipe locked: V0
Gerhard finalized the recipe in kleiner-brauhelfer. Munich Malt bumped to 23%, Caramel Amber replaces Caramel Dark, East Kent Goldings take over the late hop additions. The grain bill is tighter, the hop schedule cleaner. Recipe V0 is the one that goes into the fermenter on Saturday.
Brew program test: full run
Gerhard ran the complete brew program through brewOS. Preheat, mash in, malt rest, saccharification rest, mash out, then a 90-minute boil with all four hop additions. Clawdbot confirmed every state transition via Telegram. The digital control loop ran end to end while Gerhard handled and approved the physical steps.
T-minus 48 hours
Recipe locked. Brew program tested. Ingredients weighed. Grainfather cleaned. Saturday at 9:00, Gerhard starts the program and OpenClaw takes the mash from grain to fermenter. 24.5 liters of Amber Lager. Everything is ready.
Brew Day: Lobster Lager V0
The real deal. At 08:26, Gerhard starts the program. OpenClaw takes control of the Grainfather over BLE. Mash in at 64 °C, malt rest at 63 °C for 35 minutes, saccharification rest at 72 °C and mash out at 78 °C. brewOS manages every step transition and every hop addition. Mandarina Bavaria goes in as a first wort hop, then East Kent Goldings and Fuggles at 75 and 85 minutes before the end of the boil. A 90-minute boil at 100 °C. The full brewery is running: Grainfather G30 on the balcony, glycol chiller cooling, wort chiller coiled and ready. 24.5 liters of Amber Lager, grain to fermenter, managed by an AI agent.
brewOS runs its first real batch
The Brew Dashboard ran the entire Lobster Lager V0 session live. Recipe Lobster Lager 1 (Nr. 201), five mash steps, four hop additions, 90-minute boil. Temperature tracking, timer countdown, hop schedule with confirmation buttons. Every addition acknowledged in real time. The system that started as a prototype two weeks ago just brewed a real beer.
Fermentation begins
Wort cooled and transferred to the Grainfather conical fermenter. Yeast pitched, temperature set to 12 °C. The glycol chiller holds it steady. Within hours the fermenter reads 11.3 °C and the heater kicks in to maintain target. Lobster Lager V0 is alive. Now we wait.
Steipete drops the Lobster on Hanselminutes
Peter Steinberger, creator of OpenClaw, tells the Lobster Lager story on Scott Hanselman’s podcast. Two mentions: first, a guy at ClawCon Vienna who installed OpenClaw for his 60-year-old dad and they made lobster beer together. Then the design agency founder who went from “I’m a normie, I never wrote code” to running 25 custom web services for his business. Peter’s been telling the agency story on Lex Fridman and other shows. The lobster keeps showing up.

ClawCamp Berlin: Gerhard takes the highlight session
Gerhard delivered ClawCamp Berlin's 6:00 p.m. highlight session at CODE University of Applied Sciences. At 68, he told the Lobster Lager story in his own words: how he turned decades of brewing experience into brewOS through experimentation with OpenClaw, while remaining the human in the loop for every physical brewing decision. He ended with 24 bottles at the bar. His verdict afterwards: “Voller Erfolg.” The feedback on the beer: “Nur positiv.”
